How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does

Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.

What acts on it

  1. Treatment promoted expression of HIF-1alpha, NF-kappaB, VEGFA, SDF-1, VEGFR2 and CXCR4, with SDF-1 and VEGFA rising in human skin fibroblasts and CXCR4 and VEGFR2 rising in endothelial cells.
